JOSEPH S. STARSON, OF SAN FRANCISCO, CALIFORNIA.

TRUSS-PAD.

SPECIFICATION forming part of Letters Patent No. 262,328, dated August8, 1882,

Application filed June 10, 1882.

To all whom it may concern Be it known that I, JOSEPH STIASSNY STARSON,a citizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented a new anduseful. Truss Pad, of which the following is a specification.

The objectof my invention is to provide a means whereby the contact orpressure of the pad upon theparts or rupture can be distributed andincreased or diminished at pleasure.

- out in the claim.

It consistsin the details of construction pointed I accomplish theobject of my invention by the means illustrated in the accompanyingdrawings, in which- Figure l is a perspective view of my improvedtruss-pad. Fig. 2 is a side elevation, partly in section.

Similarlettersrefer to similar parts throughout both views.

I construct my pad-plate A of any non-absorbent material, and upon theback part thereof is placed the usual studs or pins for connecting withthe belt usually employed for holding the pad in position. Upon the faceof this plate I place a series of screw studs or pins, B, and these pinsmay pass through the plate and be permanently secured thereto. Thesestuds are provided with balls or knobs U, a fine thread, 0, being cut ineach to receive the screw-thread upon the pins or studs, so that theballs or knobs can be raised or depressed upon the pad-plate in aregular or irregular manner to suit the exigencies of the case. Forinstance, the outer row or series,

which are attached to the studs around the edge of the pad-plate, canall be elevated above the inner series and be made to sur- (No model.)

round the edge of the rupture; or the inner series may be raised orelevated and the outer ring or series depressed, so as to form aprojection couformin g to that of the ordinary pad; and, again, theballs, knobs, or protuberances may be so arranged on the screw-studs asto project at several distinct points or intervals around and upon thetissues of the parts affected, the arrangement being such as to beentirely independent of any truss-spring What- The balls may beconstructed spherical, as shown, elongated, or oval, or of any othershape to suit the exigencies of the case, and be made of any suitablematerial.

It should here be observed that not alone by this construction canpressure be removed or exerted at several or distinct points aroundandupon the rupture, but that the parts are open and exposed to the freeaction of air, which is so essential to rapid healing of suchdifficulties.

Having thus descl ibed my invention, what I claim, and desire to secureby Letters Patent, is-

In a truss-pad, the combination of a series of small balls, furnishedwith female screwthreads, with a series of screw-shafts insertedvertically in the face of the pad-plate, and upon which the balls adjustvertically, substantially as described.

In testimony that I claim the foregoing I have hereuno set my hand andseal this 31st day of May, 1882.

JOSEPH S. STARSON.
